Dark fermentation is a bioprocess driven by anaerobic bacteria that can produce hydrogen (H2) from organic waste and wastewater. This review analyses a relevant number of recent studies that have investigated dark fermentative H2 production from wastewater using two different types of anaerobic biofilm reactors: anaerobic packed bed reactor (APBR) and anaerobic fluidized bed reactor (AFBR). The effect of various parameters, including temperature, pH, carrier material, inoculum pretreatment, hydraulic retention time, substrate type and concentration, on reactor performances was investigated by a critical discussion of the results published in the literature. Also, this review presents an in-depth study on the influence of the main operating parameters on the metabolic pathways. The aim of this review is to provide to researchers and practitioners in the field of H2 production key elements for the best operation of the reactors. Finally, some perspectives and technical challenges to improve H2 production were proposed.
暗发酵是一种由厌氧细菌驱动的生物过程，它可以从有机废物和废水中生产氢气（H2）。本综述分析了大量最近的研究，这些研究使用两种不同类型的厌氧生物膜反应器：厌氧填充床反应器（APBR）和厌氧流化床反应器（AFBR），从废水中进行暗发酵生产 H2。通过对文献中发表的结果进行批判性讨论，研究了各种参数（包括温度、pH 值、载体材料、接种物预处理、水力停留时间、底物类型和浓度）对反应器性能的影响。此外，本综述还深入研究了主要操作参数对代谢途径的影响。本综述的目的是为氢气生产领域的研究人员和从业者提供反应器最佳运行的关键要素。最后，提出了一些提高氢气产量的观点和技术挑战。
